REUBEN K. NIEOE, OF FRENOHTOWVN, NEW JERSEY.

CULTIVATOR.

SPECIFICATION forming part of Letters Patent No. 243,951, dated July 5,1881.

Application filed May 5, 1880. (No model.)

To all whom it may concern:

Be it known that I, REUBEN K. NIEoE, a citizen of the United States, residing in Frenchtown, Hunterdon county, New Jersey, have invented certain Improvements in Cultivators, of which the following is a specification.

My invention relates to certain improvements in the cultivator for which Letters Patent of the United States No. 207,767 were granted to me on the 3d day of September, 1878, the objects of my present improvements being to strengthen the frame of the machine and decrease the weight of the same, and to provide for the ready shifting of the cultivatorblades from oneside of the machine to the other, so as to turn a furrow either toward or from the center of the machine. These objects I attain in the manner which I will now proceed to describe, reference being had to the accompanying drawings, in which- Figure 1, Sheet 1, is a perspective view of the frame and plows of my patented cultivator; Fig. 2, a perspective view of the frame and plows of my improved cultivator; Fig. 3,

Sheet 2, a longitudinal section of Fig. 2; Fig. 4, a sectional plan and Fig. 5, a detached view of one of the plows and its shank.

The main frame is the same in both the patented cultivator and in the improved cultivator, said frame consisting of the diverging side beams, A A, front transverse beam, B, rear transverse beam, D, and vertical supportingposts B and D, each of the beams B and D having near each end a series of openings for the reception of the bolts by which they are confined to the posts, whereby the beams A A maybe adjusted from or toward each other, as the character of the work to be done may suggest. Each of the beams A has at the front end a supporting-shoe, E, and carries a series of plows, F, two plows on each beam being shown in the present instance, but the number being varied in practice as desired.

A plow-carryin g frame projects in ward from a point near the rear end of each of the side beams, A. In the patented cultivator this frame consists of a bar, a, and a vertical rod, 1), the upper end of the latter being bolted to the beam D, and its lower end being adapted to an eyebolt, d, on the inner end of the bar a, said eyebolt being connected to the rear end of a bracing-rod, j, which extends to one of the posts B and is connected thereto. The outer end of each bar a-is bolted to one of the beams A, and said bar and the transverse beam D are provided with a series of bolt-openings, whereby the frame comprising the bar a and rod 1) may be adjusted laterally in respect to the main frame.

In my improved cultivator I discard the bars a and rods b, and use in place of the same a pair of right-angled bars, G, of metal, preferably of wrought-iron, the end of the horizontal arm of each bar being connected to one of the side beams, A, and the end of the vertical arm of said bar to the transverse beam D, a bolt at or near the angle of the bar serving as the means of connection of the bracing-rods f.

In the patented cultivator the plows F of the beams A and the plows J of the bars a are secured in position by passing the shanks of the plows through openings in the said beams and bars and retaining them by means of wedgekeys.

In my improved cultivator the beams A are provided with castings m, each of which has a projection, n, to which the shank of the plow is hung by a suitable pin, the said shank fitting between ears on the casting m and being retained in position by a transverse pin of wood, which breaks and allows the plow to yield in the event of any undue strain thereon. The shanks of the plowsJ are hung to the vertical arms of the bars G, and are retained between ears on said bars by transverse pins, in the manner set forth. The castings m and the vertical arms of the bars Gr may each have a series of openings, if desired, so as to permit the vertical adjustment of the plows F and J The shank s of each plow has, near its upper end, two threaded stems, 12, one projecting from each side of the shank, and each provided with a nut. These stems serve as pivots whereby the plows may be hung to the castings m or bars G, stems on opposite sides of the shank being employed, in order that the plows may be readily shifted from one side of the machine to the other, so as to turn furrows either from or toward the center of the machine.

When it is desired to use a supplementary bar, M, such as shown by dotted lines in Fig. 4, the rear end of said bar may be secured to the bolt whereby the rear end of one of the braces f is secured.

I have not shown in the drawings either the draft apparatus of the cultivator or the guiding-handles, as my invention has no relation to these parts. 7

The substitution of the bars Gfor the frames comprising the bars a and rods 1) reduces the weight and increases the strength of the cultivator, and imparts a neater appearance to the frame, besides facilitating the hanging of the plows J J.

I claim as my invention- 1. The combination of the side beams, AA, and transverse beam D of the machine with the right-angled bars G G, of metal, the bracing-rods f f, connected thereto, and the plows J J, the stems of which are hung to the vertical portions of the bars Grand fit between lugs thereon, said lugs carrying pins, as described, whereby the plows are retained in position, all substantially as set forth.

2. The combination of a beam, A, and a plow having a vertical shank, s, with a supporting device, m, adapted to be bolted to the beam and having an upward projection, 12, to which the shank sis pivoted, and ears which embrace said shank and project rearwardly beyond the same and are provided with openings for the reception of a retaining-pin, as set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
